Could you show the steps on how to complete this so I know how its done?

When I was a senior in college, I performed a psychology test to see which gender is more honest. I left a wallet with money and ID in a store and videotaped the results. 30 out of the 37 women returned the wallet and 29 out of the 43 men returned the wallet. Round proportions to 3 decimals. Construct a 90% confidence interval for the true difference between the proportion of men and women who will return the wallet.

Thank you
